Title: Zoom lens
Inventor: SUZUKI NORIYOSHI
IPC: G02B15/173
Filed: 1988-08-19
Abstract: PURPOSE:To obtain a simple four-group zoom lens, which is constituted of a relatively smaller number of lenses, but has a high optical performance over the full variable power range of about three in variable power ratio by specifying the lens constitution, such as the lens shape, refracting power, etc., of each lens group. CONSTITUTION:A 1st lens group I has positive refracting power for focusing and a 2nd lens group II has negative refracting power which monotonously moves to the image surface side at the time of variable power. A 3rd lens group III has positive refracting power which moves along the optical axis while a convex-like locus is held in order to maintain the image surface that varies at the time of variable power at a fixed position and a 4th lens group IV has positive refracting power which makes fixed image forming actions. In addition, the refracting power of the 2nd to 4th groups is set as expressed by Inequality I. The fi and fw of the inequality respectively represent the focal distance of the i-th group and focal distance of the entire system at a wide angle end. Therefore, a four-group zoom lens, which is constituted of a smaller number of lenses, but has a high optical performance because the variation of aberration associated with variable power of about three in variable power ration is well corrected, can be obtained.

Abstract: PURPOSE: To obtain a magnetic recording medium having high electromagnetic conversion characteristics capable of dealing with pressures from a low pressure to a high pressure by impressing positive potential on an electrode which is a counter electrode of an insulated rotary drum impressed with high-frequency pulses of a required frequency and forming a protectire film of the required polymerized film. CONSTITUTION: The high-frequency pulses of 50 to 450kHz are impressed by a high-frequency power source 2 on the insulated drum 6 and the positive potential is impressed on the electrode 1 which is the counter electrode of the drum 6. The protective film is formed by forming a hydrogen-contg. plasma polymerized film on the magnetic layer of a tape sample which is let off by the drum 6, guide rollers 8, etc., in this state. The protective film is then made into the film having high hardness, high durability, low friction and good film thickness distribution. The magnetic recording and reproducing tape 5 which is capable of dealing with the pressures from the low pressure to the high pressure and has the enhanced electromagnetic conversion characteristics is formed.

Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device in which thin lines and isolated points can be favorably reproduced even in the case where a photosensitive drum of positive chargeability and toner of positive chargeability are used. SOLUTION: Using a photosensitive drum 20 of positive chargeability and toner 53 of positive chargeability, a development roller 56 is pressed to the photosensitive drum 20 to perform impression development.

Abstract: PURPOSE:To solder outer leads positively to a printed board by connecting the outer leads firmly to metallized wiring layer. CONSTITUTION:Outer leads 6 are cut off, at first, from sealing resin 5 in straightly extended state. Metallized wiring layer 8 is formed on the top, side, and bottom faces of a discrete component, i.e., a square ceramic insulating frame 7, to be connected with the outer lead 6 at positions corresponding therewith. The insulating frame 7 is then bonded to the outer lead 6 of semiconductor device cut off from the sealing resin. The double structure prevents deformation of the outer leads in a semiconductor device. Furthermore, Au plating on the surface of the outer leads 6 and Au metallization 8 on the insulating frame 7 eliminate the need for solder plating step resulting in significant cost reduction and shortening of manufacturing process.

Title: Method for supplying oxygen gas for improving productivity of smelting reduction
Inventor: HIRATA HIROSHI
IPC: C21B11/02
Filed: 1990-08-06
Abstract: PURPOSE:To drastically increase an oxygen gas flow rate possible to supply and to improve productivity by converting a part of oxygen jet force injected from a nozzle in a top-blowing lance into rotating force to molten material in a furnace. CONSTITUTION:In the metallurgical furnace, in which gas can be top-blown, while top-blowing the oxygen, iron raw material containing iron oxide and carbonaceous material are added. Then, reduction reaction of the iron oxide in slag 3 is progressed, and the produced molten iron alloy is settled in the molten metal 5. Further, nozzle structure of the oxygen top blowing lance 1 is regulated with two angles alpha and beta so that center axis of the nozzle does not intersect with the center axis of the lance 1. By blowing with such nozzle, rotating torque is developed to the lance 1. As this lance is mechanically restricted with a lance fixed device 7, horizontal rotating force is applied in the molten material as reaction and the rotating movement is developed. In this result, while maintaining efficient operational condition to smelting reduction, by making oxygen supplying velocity high, the productivity can be improved.
